First of all, make sure that you only alter clothes from creators that allow you to do so. Some don't.

There is a way to make YA clothing available also for adults but then you need SimPE, which you can download from this site: http://sims.ambertation.de

Open it up, click on Plugins and choose scan folders. Then choose the folder (on top of the next box that shows) where you have the clothes, most often the downloads folder or savedsims and then click on the little scan button on the right side.

Then click once on the clothing you want to change so that it becomes highlighted. Then click on the operations tab down in the left corner. Scroll down to Set ages and add the adult age by ticking the box. Then click on Set ages. Close SimPE.

how about enabling adult clothing for yas, how d´you do that?

That's covered in Faylen's "converting clothes to different ages" tutorial which you will find in the tutorials area at the top of this forum.
